To all whrmt it hwy concern.-

Be it known that I, WILLIAM E. NIECE, a citizen of the United States, residing at Sandy Lake, in the county of Mercer and State of Pennsylvania, have invented cer tain new and useful Improvements in Dish- Washing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention refers to improvements in dish-washing apparatus, and has for its objects to provide a basket support adapted to be transported along a supporting trolley bar or red, said support comprising a casing containing a compression-spring with supporting trolley-wheels and a framework depending from the sprin adapted to carry the dish-containing basket, together with a securing-latch and other features of detaii, as shall be more fully hereinafter described.

The apparatus is designed to support a basket adapted to contain a considerable number of dishes and to be used in combination with one or more washing chambers or tanks, preferably two, for washing and rinsing, into which the basket is lowered and reciprocated up and down by the operator while depending from the supporting-spring. The principal function of the spring is to facilitate the up-and-dowu washing operation, thereby rendering it merely necessary to apply su'liicicnt downward pressure upon the basket to immerse the contents in the water of the tank, the spring acting to raise it'and to farilitzttc the operation, while greatly reducing the labor of the attendant.

figure 1 is a view in side elevation of my improved dish-washing apparatus, showing the dish-hohiing basket-in position for immersion over one of the chambers of the washing-tank. Fig. 2 is an end elevation thereof, showing the basket innnersed in the tank, said tank being in section. Fig. 3 is an od vr-riii-al scci'ionai view on the line iii iii of Fig. 1, showing the basket tipped in position for being filled. Fig. e is a simiiar section at right angics to Fig. 3, the basket being shown in its normal position. Fig. 5 is s cros. tional detail view on the line V v of Fig. 4. Fig. (5 is a vertical sectional view similar to Fig. 4, iiiustrz'iting a modified construction wherein thev supporting-rods are entirely ini'losod within the spring-casing.

Referring now to the drawings, wherein the invention is illustrated, 2 2 represent the com mrtlnenis of a double tank which are preferably provided with heaters 3 of any suitable kind and the usual supply-faucets and waste-pipes incident to apparatus of this character. While I have shown an arrangement of two tanks, it is obvious that a singie one or three or more tanks may be employed, the advantage of a plurality of tanks being that the dishes maybe washed in one water and subsequently washed in the other or others of the series.

4 is the basket, composed of a suitable framework of wire or similar material having a surrounding body portion of wire-netting or suitable perforated material, the basket being preferably rectangular in form and of a size adapted to freely enter the interior the tank with sufficient surrounding clearance-spacesay about one inch on each sidefor circulation of the water. An advantage of such construction is that the basket practically fills the interior of the tank, and as it is forced downwardly through the water the water will be caused to circulate upwardiy through the interior of the basket and around the contents, thoroughly Washing them and removing any adhering matter. A further advantage is that any splashin or overflow of the water is prevented, the asket acting as a plunger, practically confining the water and forcing it to pass through the basket and around the contents, as stated.

For the purpose of resiliently supporting the basket I provide the framework consisting of supporting rods or bars 5 5, crossed at 6, as shown, thereby providing a convenient handhold for the operator and terminating in oppositely-directed arms 7 7, depending downwardly and provided with terminal hooks 8, upon which the bails 9 9 of the basket are carried. The bars 5, preferably formed of an integral piece, are arranged downwardly along a spring-casing i0, having in its interior a compression coiled-spring 11, upon which the upper cross portion 12 of i3being provided at each opposite side of the case, thereby permitting suiiicicnt downward travel of the supporting-frame to entirely im merse the basket. The rods 5 of "he l'rs me are engaged by guides it, extending out-- wardly on opposite sides of the casing.

The casing consists of a section of tubing or pipe and is provided at its bottom portion with a plug 15, upon which the spring ii rests, as shown, while the upper portion is closed by a two-part bearing id,

supporting-rods 5 rests, a suitable vertical slot said plug and bearing being suitably secured in the lower and upper ends of the tube byany suitable means as by screw-threads, screws, or rivets. For the purpose of supporting the entire casing and framework I have provided the trolley-frame 17 which may conveniently be made of a single .bar of metal, as shown, passing through the two-part bearing 16, having the o ipositely extending arms deflected ontwaroi y beyond the center, as shown at 18, and terminating in inwardlyturn'ed horizontal gudgeons or studs 19, pro; vid ing trolley-wheel bearings. The trolleywheels are mounted on these hearings cen trally over the spring case, as shown in Figs. 2 and 3, and are preferably concave 'or grooved, as shown, adapted to travel upon the trolley-bar 21, supported upon suitable brackets 22 from the wall or ceiling. The trolley-bar 2'1 may conveniently be made of pipe, slotted at one side, so as to provide or the insertion at intervals of the supporting-brackets 22, thus providing a cheap convenient construction, and the supporting- Wheels 20 are so located with relation to the offset portion 18 of the frame and to the top of the two-part bearin 1'6 that there is just suiiicient clearance or the longitudinal travel of the frame, while disengagement from the trolley-bar will he ciiectually *Dreyented at all points,

, iDepending downwardly from the lower portion of the spring-tube or iroin the plug 15 thereof is a springdatch '23, having a hook 24, adapted to engage the basket-supporting portion of the train-e, as the handle 6, so as to efiectually hold it against vertical movement until the spring latch is detached. This latch is provided with a downwardlyextending thumb-terminal 25, by which the operator may detach the some from engagement while holding the. heme, or ii may be detached by the other hand.

When being filled, the basket is preferably tipped upvi' ardly into the position shown in Fig. 3, in which position it may conveniently be held by a supporting-hook 26v at one side, or it may be set upon an inclined table or support for the same purpose. liy this means the basket may be always filled or emptied While supported upon the hooks, thus obviating the necessity of lilting or moving the basket by manual power. This is of great advantage and allows oi the use of the invention Without the exertion ol espeoial strength. in. this position it may he more easily filled with dishes Without dun gcr of breakage or oi subsequent shifting, and when filled is normally supported in the horizontal position shown in Figs. 1 and i, when it is ready for innncrsion.

In Fig. 6 l show a modified construction of the spring-s1rppor-ting shell and basket-carrying irame wherein the rods 5 extcndupthe spring at the top by nuts 27' on the ends of the rods or in any other suitabie manner. In this construction a latch-holding bearing 28 is provided above the handle 6, thereby preventing interference with the hand. The advantage of this construction is that the framework is entirely inclosed within the casing, the rods passing upwardly through the bottoinportion, while the. arrangement of the parts and their method of operation are otherwise the same as has been described.

'It will be understood also that the basketsupporting frame may be secured to the lower end of an expansion-spring oi any suitable construction. I

The operation of the invention will be readily understood from the foregoing description. After having been filled with dishes at any convenient point the basket is carried by the trolley into a position above one of the tanks 2, whereupim the le.tcli-hooi is released and the operator then presses downwardly, forcing the basket and its "contents through the water in the tank, "as has been stated. The operation of pressing down and lifting up by the spring is coininued sufiieiently long to thoroughly cleanse the dishes, the strength of the spring bein such as to practically counterbalance th Weight of the basket and its contents, thus rendering the o aeration very eoinparati eiy easy, after which the same operation may be repeated in one or more of the adjacent tanks,

the surplus Water allowed to drain when a the Washed dishes may be again carried along upon the trolley to any desired point and removed from the musket.v

The, advantages of in readily appreciated by all those familiar with the operation of washing dishes, particularly in large-ninnbers-as in restaurants, hote'is, &c. it is very thorough in its "action, has ket acting as a plunger and forcing the Water with eonsidm'able pressure against the at. all sides. while no especial cars necessary in placing the dishes in the basket, inasmuai us the regurgitation oi the water in all directions insures the washing 0i every ,surface.

It will beundcrstood that the apparatus may be coi'iveniently installed in suitable relation with :n'roinpanying tables or other elements oi culinary equipment, also that the device may be changed or varied by "the skilled nioi-hanic as to its details or various features of constriu-tion; but all such changes are to be considered as Within the scope oi the follow ing claims.
